Control of Pulsations and Vibrations in Hypercompressors for LDPE Plants

Abstract

Always growing capacities, size of machines and performance requirements and often changing plant layout arrangement, determine a continuous challenge for designers of machines and plants. For hyper compressors and connected piping system, the goals of safety and reliability can be achieved only with a deep analysis of all operating conditions to determine pulsations and vibration effects. Innovative methods of simulation, modeling and technologies improve the possibility to evaluate piping and compressor behavior, allowing to obtain the efficiency and a smooth and safe plant operation.
